[Bug 39315] Keyboard random repeat

Tue May 16 22:11:14 UTC 2006

Public bug reported:

Hi all

I have a problem that my keyboard will seemingly at random start
repeating itself or do nothing at all.

i.e I might get something like this:

  hellllllllllllllllllllllllllllloJkes
in place of
  Hello Jakes 

Also happens to function buttons i.e. ctr, shift, alt, and in very rare moments the mouse buttons, this could be a red herring as I can only remember this once, could it be the "enter" key that was stuck?

I have a Dell INSPIRON 5150 notebook and the problem started when i upgraded from ubuntu breezy to ubuntu dapper, i had upgraded from hoary to breezy before. Runnin GNOME.

A few observations 
1. The problem seems to get worse with the heaver the load on the box.
2. The problem seems to disappear in run level 1 but this may be a red herring and related to observation 1.
3. The longer the box is on the more this problem seems happens.
4. ssh'ing into the box does not have the problem.
5. The problem is a lot worse in a virtual term i.e. "ctr-alt-f1". Here the problem gets so bad that only in very few instances have I been able to log in. The virtual term also seems to do random carriage returns in the login phase. Once in a virtual term I have almost never been able the "ctr-alt-f7" out of them.
6.  I have tried using a external usb keyboard, the problem 6, me 0, the problem is still there.

Things that i have tried
1. The only way to work with out smashing my fist through my keyboard is to turn auto repeat off under System --> Preference --> Keyboard

2. I have tried the "modprobe psmouse rate=40" problem still there and
cant tell if better or worse.

3. Making changes to my xorg.conf file, no difference.

Have checked my dmesg for any thing "key".
#  dmesg | grep -i key

  [4294672.443000] input: AT Translated Set 2 keyboard        
  as /class/input/input0

and acpi (see end of doc)

Please if there is any thing else or help that some one needs i am
willing to help as this problem is not only driving me mad but killing
my productivity at work.
